Abstract :
Designed by STMicroelectronics for the embedded market, the STxP70 processor is a small but extensible processor: designers have the possibility to define tightly-coupled extensions that can be reused in different designs. We explain why this modularity has a strong impact on the toolchain, detail the hardware/software flows and give results for two extensions.
